It leads to the key to doing calculus involving trig functions: limx→0sin(x)x=1 The proof has to rely on the geometry of right-angled triangles, since that’s where the sine function comes from.area of ΔOAB< area of wedge OAB< area of ΔOBD sin(x)2<x2<tan(x)2 ...

Polynomials and poly-type functions: –General tip: try factoring, then cancel common factors. –Large arguments: the largest-degree term dominates, so divide and multiply by that term. Trig and inverse trig functions: –General tip: know the graphs of all the trig and inverse trig functions,...

sure, we can establish the continuity of some functions without too much trouble, and as long as we stay in that little family of functions, we can forget about how we established they were continuous in the first place (the "only need to prove something once motto"). but even with func...
It will stop the motor and reverse the direction of spin. This can be enabled with $E. The display will show R on the screen until you start it again (double click). It will also show R and then the speed you are in. The speeds and other functions are the same, except they are...
